No sound is heard from the SWF-BR100 Wireless Subwoofer when the USB device is connected using a USB hub.

Connecting a USB device to the TV via a USB hub is not recommended and not supported. There will be no audio output from the Wireless Subwoofer and the power indicator on the subwoofer will be lit red. To resolve this, connect the USB device directly to the USB port of the TV.

If the issue is not resolved after following the troubleshooting above, service may be required.
